RB960PGS PoE in "48V" Wiring Compatibility?

Will the RB960PGS function with any "48V" source such as Mimosa PoE or UBNT 48V PoE? Will it work with a 4 pair power source, or will that cause damage? Specifically:

1. Mimosa Large PoE provided with Mimosa A5 radios
Output: 56V DC 0.93A
Pins 3/6 and 4/5: +56V
Pins 1/2 and 7/8: GND

2. Mimosa Small PoE for Mimosa C5
Output: 56V DC 0.275A
Pins 3/6: +56V
Pins 1/2: 0V

3. UBNT POE-48-24W-G
Output: 48V DC 0.5A
Pins 4/5: +48V
Pins 7/8: 0V

Thank you, Chris

According to specs on routerboard.com:
It also supports passive or standard 802.3at/af PoE input/output. Ethernet ports 2-5 can power other PoE capable devices with the same voltage as applied to the unit. Less power adapters and cables to worry about! It can power af/at mode B (4,5+)(7,8-) compatible devices, if 48-57 input voltage is used.
So it looks it will work with any of the suggested PSUs. However on brochure only passive poe-in is stated, so I'd write support if don't want to experiment which one, if the brochure, or the specs on routerboard is right.

Bear in mind the RB960PGS will feed its devices with same voltage.
